The Tactile Internet is expected to be an extremely robust and reliable system that supports consistent user experience and tactile applications/services in a connected world. To realize this vision, several technologies like Fiber-Wireless (FiWi) access networks, cloud based platforms, robotics etc. are expected to converge by the end of this decade. We will investigate key enabling techniques and architectures to improve the overall system performance. We expect that the outcomes of our project will significantly reduce the end-to-end delay for tactile applications and will inquire into new ways of complementing, rather than substituting, men with machines.
Two-level cloud-cloudlet architectures leverage both centralized and distributed cloud resources and services, whereby the cloudlet infrastructure is typically based on data-centric FiWi access networking technologies. Cooperative automation is a key feature that is expected to enhance unified FiWi and Het-Net networks by means of artificial intelligence (AI) based mobile edge-computing (MEC) capabilities. This research project will address the key challenges towards enabling AI based MEC in FiWi enhanced 4G networks to meet key design requirements such as ultra-low latency. Moreover, TensorFlow, an open source machine-learning library, will be exploited to realize collaborative automation as an important stepping stone towards human-robot symbiosis.
Cloud Computing for Smart Grids and Smart Cities
There exists a plethora of readily available wired and wireless networking technologies to build smart grid communications infrastructures. The major roadblocks toward a sustainable low carbon society might be less technological feasibility and maturity but more the lack of compelling business cases and regulatory frameworks for emerging smart grids. Similar problems have been faced during the early appearance of cloud computing in the 1960s, while now cloud computing is widely deployed. This research project aims at unveiling the potential and limitations of cloud computing in smart grids and exploring the role of cloud computing assisted smart grids as enablers for smart cities.
Advanced WBANs for an Ageing e-Health Society
As societies around the world will face populations with a significant increase of people aged over 65 years during 2010 and 2030,
it will be key to find more cost-efficient healthcare solutions. This project aims at investigating advanced wireless body area networks
(WBANs) and examining the involved challenges, including energy-efficient MAC protocol design, interoperability, as well as co-existence
and integration with FiWi access sensor networks.
Unveiling the Hidden Connections between E-mobility and Smart Microgrid
Electric mobility (e-mobility) and smart microgrid are two different game changing concepts for sustainable transportation and energy solutions. This research project aims at unveiling the hidden connections between local intermittent renewable energy sources and the stochastic characteristics of electric vehicle use patterns, thereby paving the way for a more holistic design of zero-emission smart zones by means of FiWi communications technologies.
Smart Grid Communications over Über-FiWi Networks
This research project inquires into fiber-wireless access sensor networks, new communications paradigms, migration paths,
and implementation models to integrate and efficiently control e-mobility, distributed renewable energy sources, and future
smart microgrid technologies.
Green Video-Dominated P-OTNs
This research explores next-generation P-OTN switch architectures with
advanced packet switching capabilities and new forwarding models, paying
particular attention to their control, evolutionary migration not only
from legacy SONET/SDH TDM but also widely deployed wavelength division
multiplexing (WDM) circuit-switched network infrastructures.
Optical Coding (OC) enabled Carrier-Grade
The purpose of this research project is to reconcile a partly sceptical
networking community with OC technologies and establish them as a
viable next step to enhance carrier-grade Ethernet network
architectures with novel OC enabled control plane and OAM processes.
Fiber-Wireless (FiWi) Broadband Access Networks
This research project investigates the design and performance of
future-proof FiWi broadband access network architectures, medium access
control and path selection protocols, and scheduling algorithms
required to ensure QoS continuity and end-to-end QoS support across
heterogeneous optical and wireless platforms.
